Lee announced the news on his Facebook page on Saturday afternoon, writing several different posts as a memorial to Nunn, who apparently passed away in his hometown of Pittsburgh.

Lee wrote:

"My Dear Friend, My Dear Morehouse Brother- Da Great Actor Bill Nunn As Most Of You Know Him As Radio Raheem Passed Away This Morning In His Hometown Of Pittsburgh. Long Live Bill NUNN. RADIO RAHEEM Is Now RESTING IN POWER. RADIO RAHEEM WILL ALWAYS BE FIGHTING DA POWERS DAT BE. MAY GOD WATCH OVER BILL NUNN."

And then continued:

"Radio Raheem. Let me tell you the story of Right Hand, Left Hand. It's a tale of good and evil. Hate! It was with this hand that Cane iced his brother. Love! These five fingers, they go straight to the soul of man. The right hand: the hand of love. The story of life is this: static. One hand is always fighting the other hand, and the left hand is kicking much ass. I mean, it looks like the right hand, Love is finished. But hold on, stop the presses the right hand is coming back. Yeah, he got the left hand on the ropes, now, that's right. Yea, Boom, it's a devastating right and Hate is hurt, he's down. Ooh! Ooh! Left-Hand Hate KOed by Love. If I love you, I love you. But if I hate you…Mookie: there it is, Love and Hate. Raheem I love you bruh…"

So sad.

Nunn made his acting debut in 1988, in Lee's School Daze, before playing Raheem (below):

He also acted in a host of other films, including the Spider-Man trilogy.

As we previously reported, Britney Spears' baby daddy has requested an increase in his $20K a month child support stipend. While it's said that Godney isn't THRILLED at the request, she's letting her poppa negotiate a deal with KFed.

And it appears that negotiations are well under way, though Mr. Spears is NOT impressed with his former son-in-law!
